Fire Safety for Underground Parking – Risks, Prevention and Protection Guide

# Fire Safety for Underground Parking – Risks, Prevention and Protection Guide

Underground parking facilities are commonly found beneath residential towers, commercial buildings, shopping complexes, hotels, hospitals and mixed-use developments.

A fire in an underground parking area can create serious challenges because smoke and heat may accumulate in enclosed spaces, visibility can become poor and emergency access may be restricted.

Vehicles, fuel, electrical systems, battery-powered vehicles and charging equipment can all contribute to fire risks.

A comprehensive underground parking fire protection system helps protect:

• Vehicle Owners
• Residents
• Employees
• Visitors
• Security Staff
• Building Property
• Electrical Equipment
• Parking Infrastructure

Fire safety is important for:

• Basement Parking
• Underground Car Parks
• Residential Parking
• Commercial Parking
